mini air conditioner for fan coil evaporative air cooler unit

Equivalent diameter of micro-channel heat exchanger is between 10 and 100 microns. Micro-channel heat exchanger is composed of header, flat tubes and fin, which is used in the refregeration industry and its main material is aluminum and aluminum alloy.

The micro-channel heat exchanger is a new type of compact heat exchanger with high coefficient that is the substituted choice of the parallel-fin heat exchanger. The system becomes main stream which has advantages of high dependability, compact in size, low weight, economical in cost and high thermal efficiency.

Features:

Micro-channel condensing units

1. Adopt the world famous compressor of copeland,so the whole unit features light vibration, low noise and smooth operation.

2. Adopt microchannel heat exchanger condenser which is effective to reduce thermal contact resistance and improve thermal transfer, low noise and long using life.

3.  The unit has characters of little area occupied, compaction of equipment, easy transporting and using.

4. Each unit was equipped with high and low voltage pressure switch, overheat and other protection.

5. Expansion valve, electric component and so other key components all adopt famous brands or domestic first-class materials to ensure the quality and life of the unit.

Advantages:

1. Higher heat transfer ( based on the same footprint)

2. Higher internal heat transfer coefficient: tubes with small section provide higher refrigerant speed and higher turbulence besides a bigger internal surface.

3. Higher external heat transfer coefficient: the overall tubes surface touched by the air is much bigger then in T&F coils.

4. Reduction on footprint( based on the same heat rejection).

5. Less air pressure drops(based on same heat rejection and same air speed value)

6. Smaller internal volume & refrigerant charge reduction.

7. Compact dimension and limited weight.

8. No risk of galvanic corrosion ( coil 100% in aluminum alloy)

9. Coil easy to recycle(100% aluminum).
